Introduction to the Process of Stone Paper Casting Paper Machine
The granules manufactured by the granulator are transported to the barrel of the machine, with quantitative screw for expected entrance, the electric heating and a strong push to squeeze and screw, make the raw material granules temperature rise and soften up to 200 ℃, and with melted PE material, squeezed into ABC three layers of "T" shape mold to form three layer composite sheet material,stretched by the two flow rollers, by controlling the speed to adjust the thickness of the product, then cooed and set by cooling wheel group, flattened, appearance inspection, thickness tested and static elimination, after cutting off the ear material on both sides and winding it .it is the stone paper protection base paper products.
The product can be used for writing and printing, and making products such as books, magazines, notebooks, advertising brochures and maps.Also can make packaging bags and other edges with hot seal demand products.
